Gambling is totally dependent on luck and experience.
Totally.. no, it also depends on your skills, your experience your earn is useless if you will not learn something to improve your skills in gambling.
Luck does not need an experience as they say luck beats talent and even experience, but it would not give you consistency.
If you are a real gambler, you obviously bet again after lose.
Definitely because you want to win back your loses and be profitable, you are not gambling just to lose, you also try to win.
You know that gambling depends on luck, you can win on second time. so, I think betting double after losing is not a bad decision, if your destiny is with you then you will win.
I think you just have to set some limit and follow your game plan all the time, no emotions involve just a pure planning that you need to properly execute.
